CROSS-REFERENCE TO RELATED APPLICATION

This application is a divisional of application Ser. No. 768,393, filed Aug. 22, 1985, which is a continuation-in-part of application Ser. No. 551,758 filed Nov. 14, 1983, both now abandoned.

BACKGROUND OF THE INVENTION

In recent years there has been a great deal of effort directed to the development of sulfonamides having herbicidal activity and several of these compounds have reached the stage of commercialization, i.e., chlorosulfuron and sulfometuron methyl. These compounds exhibit both preemergence and postemergence activity against undesirable vegetation and, in addition, have a low toxicity to mammals. The compounds of the prior art may be depicted as follows: ##STR1## wherein Ar is usually a benzene derivative and Ar' is usually a pyrimidine or symmetrical triazine derivative.

In addition, there are a number of other sulfonamide herbicides that have been commercialized, for example, methyl sulfanilylcarbamate; O,O-diisopropyl phosphorodithioate-S-ester with N-(2-mercaptoethyl)benzenesulfonamide; 3-isopropyl-1H-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide; N-[2,4-dimethyl-5-[[(trifluoromethyl)sulfonyl]amino]phenyl]acetamide and 3,5-dinitro-N⁴,N⁴ -dipropylsulfanilamide.

SUMMARY OF THE INVENTION

We have now found that compounds having the formula: ##STR2## wherein Ar represents an aromatic (substituted or unsubstituted) or heteroaromatic (substituted or unsubstituted) ring system wherein the substituents are electron withdrawing function groups in combination with other organic functional groups are exceptionally active herbicides and are active in the suppression of nitrification of ammonium nitrogen in soil and are effective in beneficially regulating the growth of crops and are readily produced. The aromatic ring may be monocyclic containing six carbon atoms or bicyclic containing ten carbon atoms. The heteroaromatic ring may be monocyclic containing five or six atoms or bicyclic containing nine or ten atoms. The heteroatoms present in the heteroaromatic ring may be one combination of one or more atoms such as nitrogen, oxygen or sulfur.

In addition certain derivatives of compounds of general formula (I) also exhibit herbicidal activity and suppression of nitrification of ammonium nitrogen in soil and effective in beneficially regulating the growth of crops and have the general formulas: ##STR3## wherein Ar represents an aromatic (substituted or unsubstituted) or heteroaromatic (substituted or unsubstituted) ring system.

DETAILED DESCRIPTION OF THE INVENTION

Furthermore, in the above invention corresponding to general formula III the existence of stereoisomerism is possible. For example stereoiosmeric relationships exist when at least one of substituents X, Y and Z does not equal hydrogen. When only one of substituents X, Y and Z does not equal hydrogen the compound of type III may exist as a mixture of enantiomers. One enantiomer will be designated as having the R-configuration and the other will be designated as having the S-configuration. Each enantiomer may exhibit different levels of herbicidal activity. When two or more of substituents X, Y or Z in structure III do not equal hydrogen, the material may exist as a mixture of diastereomers. For example when two substituents among X, Y and Z do not equal hydrogen, the compound may exist as two diastereomers. When all three of substituents X, Y and Z do not equal hydrogen the compound may exist as four diastereomers. In addition all of the diastereomers described above exist as a mixture of two enantiomers. All of the stereoisomers described above, diastereomers and their enantiomeric pairs, may exhibit different levels of herbicidal activity.

The synthesis of compounds of general structure I can be carried out in a straightforward manner as illustrated in Scheme I. Reaction of sulfonyl chloride IV with the appropriate aromatic (substituted or unsubstituted) or heteroaromatic (substituted or unsubstituted) amino compound (ArNH₂) under basic conditions yields the desired product I. A wide range of solvents may be employed (i.e., CH₂ Cl₂, CH₃ CN or pyridine) at temperatures ranging from 0° C. to reflux. Bases which serve as catalysts include pyridine, 4-dimethylaminopyridine and tertiary alkylamines such as triethylamine or N-methylmorpholine. Generally the amino compound serves as the limiting reagent. Molar ratios of between 1.1 and 1.0 for the sulfonylchloride to amino compound and molar ratios of between 5.0 and 1.1 for the base to amino compound are used most often. A wide range of concentrations may be employed (i.e., 0.1-5M). Generally concentrations in the range of 0.5-2M are used to give a homogeneous reaction which proceeds at a convenient rate. In addition it is sometimes advantageous to use a combination of pyridine derived base catalysts and tertiary amine bases. The use of pyridine as a solvent is convenient as the pyridine can serve both as a solvent and catalyst in the transformation. ##STR13##

An additional alternative route to compounds of general formula I is illustrated in Scheme I. In cases where the amino compound (ArNH₂) is less reactive (less nucleophic) is it advantageous to prepare a metal derivative of the amino compound by treatment with a strong base. The corresponding amide bases are generally prepared in ether solvents (i.e., THF) using strong bases such as alkali metal alkyls (i.e., n-BuLi) or alkali metal hydrides (i.e., NaH or KH) at temperatures ranging from -80° C. to 0° C. The amide thus generated in situ can be reacted with sulfonylchloride IV to yield the desired product I. Generally, molar ratios of the starting amino compound to sulfonyl chloride of 2 to 3 are used to ensure complete reaction.

Sulfonyl chlorides IV are new and represent key intermediates in the synthesis of sulfonamides I. Sulfonyl chlorides IV may be prepared according to routes outlined in Scheme II. Mercaptan IV may be converted to sulfonyl chloride IV by treatment with Cl₂ in an aqueous acidic medium. Generally the medium would be aqueous acetic acid or aqueous HCl. The temperature of the reaction mixture is generally maintained between -20° C. and 25° C. during the course of the chlorine addition. Most preferably, temperature ranges between -20° C. and 0° C. are employed to minimize unwanted side reactions such as hydrolysis of IV to the corresponding sulfonic acid. Alternatively, the mercaptan IV may be suspended in a two phase system of aqueous acid (i.e., HCl) and an organic solvent (i.e., CH₂ Cl₂) and treated with sodium hypochlorite. This serves to convert IV to the sulfonyl chloride IV in a reproducibly good yield. The solubility of the product in the organic phase serves to protect it from hydrolysis to the sulfonic acid. Again, temperatures in the range of -20° C. to 25° C. are employed with temperatures in the range of -5° C. to 5° C. being most generally used. ##STR14##

As an alternative, it is sometimes preferred to prepare sulfonyl chloride IV from benzyl sulfide VI (Scheme II). Reaction conditions as described above for the conversion of V to IV are operable. This procedure yields by-products containing benzyl residues which are generally removed by washing the product with water and/or an appropriate organic solvent and drying in vacuo.

Compounds of general structure V or VI may be prepared by routes illustrated in Scheme III. Some derivatives of structures V and VI are known materials (i.e., V X═Z═Me, Y═H and VI X═Z═Me, Y═H) prepared by methods described in J. Med. Chem., 25, 420 (1982). Compound IV is prepared directly by reaction of a 1,3-diketone with commercially available 3-amino-5-mercapto-1,2,4-triazole VII in glacial acetic acid as a solvent. Generally the reaction is performed at reflux. Alternatively, VII may be benzylated with benzyl chloride using an alkali earth metal alkoxide (i.e., NaOH) as a base to yield known benzyl sulfide VIII (J. Heterocycl. Chem., 12, 1187 (1975)). Benzyl sulfide VIII can be condensed with not only 1,3-diketones but also β-keto esters, malonic esters, malonaldehyde, β-ketoaldehydes or α-formyl esters or derivatives thereof (i.e., acetals or enol ethers) to yield products of type VI as illustrated in Table A. Generally these reactions can be carried out under acidic conditions (i.e., glacial acetic acid as a solvent) or basic conditions (i.e., NaOR in ROH wherein R is C₁ to C₄ alkyl). In cases where the X, Y and Z substituents in VI are derived from a 1,3-diketone, compound VI may be prepared by benzylation of IV using an appropriate base (i.e., NaOH) and benzyl chloride in a variety of solvents (i.e., H₂ O, CH₃ OH, EtOH, THF, dioxane, CH₃ CN, DMF or DMSO or combinations of the aforementioned). ##STR15##

Clearly this is the equilibrium with the various keto           forms.                                                                   

In instances where the 1,3-dicarbonyl compound is unsymmetrical, the possibility of obtaining two different isomers from condensation with VIII exists. In general, under acidic conditions the exocyclic nitrogen in VIII is the first to condense with the 1,3-dicarbonyl compound. Under basic conditions the endocyclic nitrogen in VIII is sometimes more reactive. Consequently, in situations where a clear difference in reactivity of the two carbonyl functionalities in the 1,3-dicarbonyl compound exists, some measures of regiochemical control may be achieved by choice of reaction conditions (i.e., entries 2 and 3 in Table I).

To prepare the alternative regioisomer to that depicted in entry 4 in Table A (i.e., VI X═R, Y═R' and Z═OH) a route illustrated in Scheme IV was followed. Compound VIII was condensed with 2,3-dibromocarboxylic acid esters to yield VI (X═R, Y═R', Z═OH). The reaction is generally carried out in refluxing pyridine. ##STR21##

An additional route to compounds of type VI involves condensation of compound VIII with methanaminium compounds of type VII as illustrated in Scheme V. The condensation is usually carried out by reaction in refluxing glacial acetic acid and is useful in the synthesis of a number of 6-substituted 1,2,4-triazolo[1,5-a]pyrimidines. ##STR22##

In the synthetic routes listed above, compounds of type VI where X and/or Z is OH are capable of undergoing further transformation (Scheme VI). For example, treatment of compound VI (X and/or Z=OH) with phosphorus oxychloride yields VI (X and/or Z=Cl). The reaction is generally carried out at reflux in neat phosphorus oxychloride or with phosphorous oxychloride in a solvent (ie CH₃ CN). Compound VI (X and/or Z=Cl) can be further reacted with nucelophiles (i.e., NaOCH₃, MeMgBr) to yield VI (X and/or Z=OCH₃ or CH₃, respectively). In addition compound VI (X and/or Z=Cl) may be reduced to afford VI (X and/or Z=H). An effective reducing agent for this type of transformation is zinc-copper couple in the pressure of acid. ##STR23##

Other compounds of the present invention are best prepared in a manner illustrated in Scheme VII. Compounds such as is represented by structure XI wherein X¹ and Z¹ are independently represented by hydrogen, C₁ -C₄ alkyl, thioalkyl, thioaryl, amino (including mono- and disubstituted alkylamino, mono- and disubstituted arylamino and arylalkylamino) can be prepared by this method. The method involves the reaction of compound X wherein X and Z independently represents hydrogen, C₁ -C₄ alkyl or an appropriate leaving group, with a nucleophile in a suitable solvent. This procedure affects the substitution of the leaving group by the nucleophilic unit. A representative leaving group that is effective in this process is trifluoroethoxide (⁻ OCH₂ CF₃). Representative nucleophiles for this process include alkali metal salts of alkyl mercaptans, alkali metal salts of aryl mercaptans, ammonia, primary and secondary alkylamines, primary and secondary arylamines, secondary arylalkylamines, and alkali metal salts of hydroxides. These nucleophiles result in the displacement of the leaving group (X and/or Z) in compound V to produce compound XI containing X¹ and/or Z¹ represented as alkylthio, arylthio, amino, mono- and disubstituted alkylamino, mono- and disubstituted arylamino, arylalkylamino or hydroxyl respectively. Suitable solvents for this transformation include polar aprotic solvents (i.c., DMSO, DMF), alcohols and water. Suitable reaction temperatures range from 0° C. to 100° C. although the temperature of the reaction is usually not critical. Reaction temperatures of 20° C. to 30° C. are most frequently employed. ##STR24##

In addition certain compounds of the present invention containg a halogen in the 6-position on the 1,2,4-triazolo[1,5-a]pyrimidine ring system may be prepared by halogenation of the corresponding 6-unsubstitued compound. This is illustrated in Scheme VIII. In general N-halo-succinimide derivatives are the halogenating agents of choice. Reactions are often performed in acid solvents at temperatures ranging from room temperature to 150° C. ##STR25##

Another method to prepare the compounds of the present invention is illustrated in Scheme IX. Compounds of general structure I can be oxidized to yield compounds of structure XII. Oxidizing agents capable of this transformation include various transition metal oxidants such as derivatives of hexavalent chromium (Cr^(VI)) or heptavalent manganese (Mn^(VII)), organic peracids or peroxides. Oxidizing agents such as potassium permanganate, chromium trioxide, peracetic acid and hydrogen peroxide are frequently employed. Preferred condtitions for the conversion of I to XII involve reaction of I with two to five molar equivalents of potassium permanganate in 0.1N to 1.0N aqueous alkali metal hydroxide (i.e., NaOH or KOH) as a solvent. The reaction may be run at temperatures ranging from ambient temperature to reflux. Most commonly the reaction is run at 50° C. to 60° C. The product of this reaction (XII) can be hydrolyzed to compound XIII by treatment with aqueous acid in an organic co-solvent. Typical acids include hydrochloric acid, sulfuric acid, acetic acid, trifluoroacetic acid or methane sulfonic acid. Appropriate organic co-solvents include acetone, methyl ethyl ketone, ethanol, acetonitrile or tetrahydrofuran. Lastly, compound XIII can be reconverted to a compound of general structure I by cyclization with a 1,3-dicarbonyl compound or an equivalent of a 1,3-dicarbonyl compound. The conditions for this cyclization, the structural requirements for the 1,3-dicarbonyl compound or an equivalent and structural considerations for the product are as described previously for the conversion of VII and V and VIII to VI. ##STR26##

The method for the preparation of compounds of structure I as illustrated in Scheme IX is employed advantageously in certain situations. Various functional groups present on the 1,2,4-triazolo-[1,5-a]pyrimidine ring system (X, Y and Z) of I which impart useful herbicidal, nitrification inhibitory or plant growth regulatory activity can only be produced in low yield by previously described routes. The primary cause for the low yield in the previously described routes is the incompatability of the function group or the ring system which bears the functional group to the conditions required to form the required sulfonyl chlorides IV. Examples of substituents (X, Y and Z) present in compounds of structure I which are advantageously prepared by the method outlined in Scheme IX include H, halo (F, Cl, Br and I), hydroxy, C₁ -C₄ alkyl, C₁ -C₄ alkoxy, C₁ -C₄ alkylthio, C₁ -C₄ alkysulfinyl, C₁ -C₄ alkylsulfonyl, C₁ -C₄ mono- or polyhaloalkyl, C₁ -C₄ mono- or polyhaloakoxy, C₁ -C₄ mono- or polyhaloalkylthio, C₁ -C₄ mono- or polyhaloalkylsulfinyl, C₁ -C₄ mono- or polyhaloalkylsulfonyl, amino, C₁ -C₄ mono- or dialkylamino, phenyl, substituted phenyl, phenoxy, substituted phenoxy, thiophenyl, phenylsulfinyl, phenylsulfonyl, substituted thiophenyl, substituted phenylsulfinyl, substituted phenylsulfonyl, carboxyl, and carboxyl derivatives such as esters derived from C₁ -C₄ alcohols. The substituents X and Y or Y and Z can also be joined to form a ring containing a total of five to seven atoms. This ring may contain heteroatoms (i.e., nitrogen, oxygen or sulfur), unsaturation (i.e., --CO--or --C═C--) or a halogen substituent.

The compounds of structure I which are most advantageously prepared by the method outlined in Scheme IX contain substituents (X, Y and Z) which are one or more of the following: H, halo (F, Cl, Br and I), C₁ -C₄ alkyl, C₁ -C₄ alkoxy, C₁ -C₄ alkylthio, C₁ -C₄ alkylsulfinyl, C₁ -C₄ alkylsulfonyl, C₁ -C₄ mono- or polyhaloalkyl, C₁ -C₄ mono- or polyhaloalkoxy, C₁ -C₄ mono- or polyhaloalkylthio, C₁ -C₄ mono- or polyhaloalkylsulfinyl, C₁ -C₄ mono- or polyhaloalkylsulfonyl, amino and C₁ -C₄ mono- or dialkylamino.

Specifically preferred substituent patterns of structure I which may be prepared by the method outlined in Scheme IX are the following:

1. X═Y═Z═H

2. X═CF₃, Y═H and Z═CH₃

3. X═Z═CF₃ and Y═H

4. X═Cl, Y═H and Z═CH₃

5. X═OCH₃, Y═H and Z═CH₃

6. X═OCH₂ CF₃, Y═H and Z═CH₃

7. X═SCH₃, Y═H and Z═CH₃

8. X═N(CH₃)₂, Y═H and Z═CH₃

The starting material of structure I in the reaction sequence of Scheme IX may contain one or more of the following substituents: H, halo (F, Cl, Br and I) and C₁ -C₄ alkyl. The intermediates (XII and XIII) are new compounds. The aromatic ring in the starting material I and intermediates XII and XIII is as described previously for structure I. The R group in intermediates XII may be H or CH₃.

Compounds of the present invention represented by structure II are derived from compounds represented by structure I as illustrated in Scheme X. The derivatization procedure involves treatment of compound I with a base in a suitable solvent followed by the introduction of an appropriate electrophilic derivatizing reagent. From this process compounds of general structure II can be isolated in good yields. Suitable bases include tertiary alkylamines (i.e., triethylamine), pyridine, 4-dimethylaminopyridine, alkali metal carbonate (i.e., Na₂ CO₃ or K₂ CO₃) and alkali metal alkoxides (i.e., sodium ethoxide or potassium t-butoxide). Suitable solvents include ethers (i.e., tetrahydrofuran), pyridine, acetone, acetonitrile, alcohols (i.e., methanol, ethanol, isopropanol and t-butanol) and polar aprotic solvents (i.e., DMSO and DMF). Suitable electrophilic reagents include alkyl halides, arylalkyl halides (i.e., benzyl chloride), carboxylic acid chlorides, alkyl chloro formates, aryl chloro formates, N,N-dialkyl carbamoyl chlorides, alkyl sulfonyl chlorides, aryl sulfonyl chlorides, alkyl chloro thioformates ##STR27## and aryl chlorothioformates ##STR28##

Compounds of the present invention represented by structure III are also derived from compounds represented by structure I as illustrated in Scheme XI. The general process involves the reduction of compounds of general structure I with an appropriate reducing agent in a suitable solvent to yield compounds of general structure III. Reducing agents which are effective include metal hydrides (i.e., sodium borohydride) in the presence of acids (i.e., methane sulfonic acid) and hydrogen in the presence of a normal hydrogenation catalyst (i.e., palladium on carbon). For reductions with metal hydrides polar aprotic solvents (i.e., DMSO) are most frequently used. For reductions using hydrogen and a catalyst alcohols (i.e., ethanol) are most frequently employed as solvents. ##STR29##

The majority of the amino compounds (ArNH₂) utilized to prepare the compounds of the present invention (see structure I) as illustrated in Scheme I were obtained from commercial sources or prepared by known literature procedures or minor modifications of literature procedures.

A number of the amino compounds (ArNH₂) used to prepare the compounds of the present invention are derivatives of anthranilic acid. Many of these compounds can be prepared according to conventional methods described by S. J. Holt et al., Royal Soc. Proc. Sec. B, 148, 481 (1958), P. W. Sadler et al., J. Am. Chem. Soc., 78, 1251 (1956), and G. Reissenweber et al., U.S. Pat. No. 4,310,677 (1982). Other anthranilic acid derivatives can be prepared by standard derivatizations (i.e., conversion to esters and amides) of known substituted or unsubstituted 2-nitrobenzoic acids followed by reduction of the nitro group as represented in Scheme XII. ##STR30##

A number of the amino compounds are prepared by reduction of anthranilic acids or esters and subsequent derivatization of the reduction product. This is outlined in Scheme XIII. The carbinol reduction products may be derivatized by reaction with base and various electrophiles (i.e., alkyl halides and carboxylic acid chlorides). ##STR31##

A large number of the amino compounds utilized in the preparation of the compounds of this invention contain halogen substituents ortho to the amino group. Many of these compounds were prepared by halogenation of the corresponding material bearing no substituent in the ortho position according to a general procedure described by R. S. Neale et al., J. Org. Chem., 29, 3390 (1964). The starting materials for these halogenations were commercially available or known in the literature (i.e., British Pat. No. 695,164 (1953); D. S. Noyce et al., J. Org. Chem. 26, 1732 (1961) and U.S. Pat. No. 3,813,234 (1974). In certain instances to facilitate the transformation and insure ortho selectivity in the halogenation process the starting materials for the halogenation were acetamide derivatives (ArNHCOCH₃) or derivatives containing groups (i.e., Br) which would block halogenation at other positions in the molecule (i.e., para to the amino group). Following halogenation the acetamide derivatives were hydrolized back to the desired amino compound and the blocking groups were removed (i.e., Br in the para position was selectively removed by reduction in the presence of --Cl in the ortho position). Other chlorine and bromine substituted amino compounds were prepared by known procedures (i.e., U.S. Pat. No. 4,188,342 (1980); C. R. Rasmussen et al. J. Med. Chem., 21, 1044 (1978); H. E. Dadswell et al. J. Chem. Soc., 1102 (1927); U.S. Pat. No. 3,813,234 (1974) and P.B.D. DeLaMare and J. H. Ridd, "Aromatic Substitution, Nitration and Halogenation", Academic Press, New York (1959), p. 106.

A number of the amino compounds used as starting materials for the compounds of this invention contain sulfur substituents in the ortho position. These were prepared using known procedures (i.e., R. R. Gupta el al Heterocycles, 16, 1527 (1981) and J. P. Chupp et al., J. Org. Chem., 49, 4711 (1984)). In some cases alkylthio groups were present and these were synthesized by alkylation of the corresponding mercaptan. Compounds having alkyl or aryl sulfinyl or sulfonyl groups were synthesized by oxidation of the appropriate alkyl or arylthio groups.

Some starting amino compounds containing amino, alkylamino, aryloxy or pyridyloxy groups were prepared by catalytic reduction of the corresponding nitro compounds. The amino, alkylamino, aryloxy or pyridyloxy group were usually introduced via displacement of a leaving group ortho to the nitro group in the requisite nitrobenzene.

Other starting amino compounds were prepared by procedures involving metalation of the aromatic ring of N-substituted derivatives (i.e., t-butoxycarbonyl derivatives) of an aromatic amino compound followed by the resulting organometallic reagent with an electrophile. This general procedure is described in H. Gschwend, Org. Reactions, Vol. 20, 1-360 (1979) and is outlined in Scheme XIV. Suitable metalating agents are organolithium reagents (i.e., n-butyllithium or t-butyllithium). Typical electrophiles include alkyl halides (i.e., methyl iodide, ethyl iodide), aldehydes (i.e., formaldehyde, acetaldehyde), ketones (i.e., acetone), alkyl or aryl sulfonyl halides (i.e., methyl sulfenyl chloride), and dialkyl or diaryldisulfides (i.e., dimethyldisulfide). These electrophiles are useful for the introduction of alkyl, hydroxy alkyl and arylthio or arylthio groups to the position ortho to the amino group. After the reaction of the organometallic intermediate with the electrophile the nitrogen substituent is removed by hydrolysis. ##STR32## e.q. x=COOtBu.

Other aromatic amino compounds used to prepare compounds of the present invention are prepared by conversion of carboxylic acid groups or derivatives of carboxylic acid groups to amino groups by standard methodology. Such a transformation is illustrated in Scheme XV and described in J. Royal. Netherlands Chem. Soc., 97, 53 (1978) ##STR33##

Other amino compounds such as those which are heteroaromatic amino compounds are prepared by known procedures such as those described in Rec. Trav. Chim., 69, 673 (1950), T. Talik et al., Chem. Abstracts, 59: 8698a (1963) and L. C. Behr and R. Fusco In "Heterocyclic Compounds", A. Weissberger, Ed. Vol 22, Interscience Publishers, New York (1967), p 3-174 or straightforward modification of the art described above.

Other amino compounds used to prepare compounds of the present invention are prepared by direct metalation of the aromatic ring. This is illustrated schematically in Scheme XVI. An aromatic ring bearing one to three substituents on the ring may be metalated with an alkyl lithium reagent (i.e. n-butyl lithium, s-butyl lithium or t-butyl lithium) to form an aryl lithium intermediate. This reaction is most frequently carried out in an etherial solvent (i.e. diethyl ether, tetrahydrofuran or 1,2-dimethoxyethane) at temperature ranging from -78° C. to ambient temperature. It is sometimes advantageous to perform the metalation reaction in the presence of additives such as tetramethylethylenediamine. The aryl lithium reagent is generated in situ and is reacted with carbon dioxide followed by protonation of the resultant carboxylate to form the carboxylic acid. The carboxylic acid can then be converted to the corresponding amino compound by standard methodology of the Hoffman, Curtius, Lossen and Schmidt reactions. ##STR34##

The substituents (R¹, R², and R³), which are operable in the process illustrated in Scheme XVI are as follows: R¹, R², and R³ may be chosen from among H, halogen (F, Cl, Br and I), C₁ -C₄ alkyl, C₁ -C₄ mono- or polyhaloalkyl or C₁ -C₄ alkoxy. Most preferred substituents are R¹ is equal to H or C₁ -C₄ alkyl; R² and R³ are equal to halo (F or Cl), C₁ -C₄ mono- or polyhaloalkyl or C₁ -C₄ alkoxy.

The intermediate carboxylic acid formed as illustrated in Scheme XVI or derivatives of the carboxylic acid (i.e. esters and amides) can be utilized to prepare other amino compounds which are useful in the preparation of compounds I of the present invention. This process is illustrated in Scheme XVII. When the carboxylic acid product contains a leaving group such as a halogen atom (i.e. F, Cl or Br) at an adjacent position, the carboxylic acid may be converted to a suitable derivative and the halogen may then be replaced by displacement with a suitable nucleophile. Nucleophiles which are useful in this case include ammonia, C₁ -C₄ monoalkyl amines, C₁ -C₄ dialkylamines, C₁ -C₄ alkali metal alkoxides, C₁ -C₄ alkali metal mono- or polyhaloxides or C₁ -C₄ alkali metal mercaptides. The use of these nucleophiles serves to replace the halogen substituent with amino, C₁ -C₄ monoalkylamino, C₁ -C₄ dialkylamino, C₁ -C₄ alkoxy, C₁ -C₄ mono- or polyhaloalkoxy or C₁ -C₄ alkylthio respectively. The resultant products of the nucleophilic displacement can be converted to the corresponding amino compound by standard methodology of the Hoffman, Curtius, Lossen and Schmidt reactions. ##STR35## R² or R³ =halogen X=OH, OR⁴ N(R⁴)₂ were R⁴ =H or C₁ -C₄ alkyl.

Other amino compounds which are sueful in the preparation of compounds I of the present invention can be prepared as illustrated in Scheme XVIII. The starting material for this procedure is 2,6-difluoroaniline. The amino group of the aniline is protected with a silyl protecting group according to a general procedure described by Magnus et. al in Tetrahedron Lett., 1787 (1981) and Guggenheim et al. in Tetrahedron Lett., 1253 (1984). The protected aniline can then be metalated with an alkyl lithium reagent (i.e. n-butyl lithium, s-butyl lithium or t-butyl lithium) to form the corresponding aryl lithium reagent. The metalation is best carried out in etherial solvents such as diethyl ether, tetrahydrofuran or dimethoxyethane at temperatures ranging from -78° C. to ambient temperature. It is sometimes advantageous to carry out the metalation in the presence of additives such tetramethylethylenediamine. The aryl lithium reagent is formed in situ and can be reacted with a variety of electrophilic reagents such as C₁ -C₄ alkyl halides, C₁ -C₄ dialkyldisulfides or C₁ -C₄ alkyl sulfenyl halides, dimethylformamide, C₁ -C₄ acryl halides or C₁ -C₄ N-methyl-O-methyl alkylhydroxamates, C₁ -C₄ alkyl chloroformates and carbon dioxide. These electrophilic reagents serve to introduce C₁ -C₄ alkyl, C₁ -C₄ alkylthio, formyl, C₁ -C₄ acyl, C₁ -C₄ alkoxycarbonyl and carboxyl groups respectively directly into the 3-position of the aromatic ring.

The compounds of the present invention are highly effective herbicides when applied to the locus of vegetation, herein defined as encompassing preemergent (soil) applications as well as postmergent (foliar) applications. They have utility for broadspectrum pre- and/or postemergence weed control in areas where complete vegetation control is desired. The subject compounds are also useful for selective pre- and/or postemergence weed control in crops such as wheat. Certain of these compounds are effective for the control of nutsedge (cyperus spp.) and some compounds may be used for selective weed control in corn, soybeans and rice.

For all such uses, unmodified active ingredients of the present invention can be employed. However, the present invention embraces the use of a herbicidally-effective amount of the active ingredients in composition form with an inert material known in the art as an agricultural adjuvant or carrier in solid or liquid form. Such adjuvants or carriers must not be phytotoxic to valuable crops particularly at the concentration employed in applying the composition in attempting selective weed control in the presence of crops. If weed control is desired in the absence of crops, it is generally sufficient to employ adjuvants or carriers which do not leave a persistent phytotoxic residue.

Thus, for example, an active ingredient can be dispersed on a finely-divided solid and employed therein as a dust. Also, the active ingredients, as liquid concentrates or solid compositions comprising one or more of the active ingredients can be dispersed in water, typically with aid of a wetting agent, and the resulting aqueous dispersion employed as a spray. In other procedures the active ingredients can be employed as a constituent of organic liquid compositions, oil-in-water and water-in-oil emulsions or dispersions, with or without the addition of wetting, dispersing, or emulsifying agents.

Suitable adjuvants of the foregoing type are well known to those skilled in the art. The methods of applying the solid or liquid herbicidal formulations similarly are well known to the skilled artisan.

Organic solvents that can be employed include toluene, xylene, kerosene, diesel fuel, fuel oil, and petroleum naphtha, ketones such as acetone, methylethyl ketone and cyclohexanone, chlorinated hydrocarbons such as trichloroethylene, and perchloroethylene, esters such as ethyl acetate, amyl acetate and butyl acetate, ethers, e.g., ethylene glycol monomethyl ether and diethylene glycol monomethyl ether, alcohols, e.g., methanol, ethanol, isopropanol, amyl alcohol, ethylene glycol, propylene glycol, butylcarbitol acetate and glycerine. Mixtures of water and organic solvents, either as emulsions or solutions, can be employed.

The active ingredients of the present invention can also be applied as aerosols, e.g., by dispersing them by means of a compressed gas such as one of the fluorocarbons or one of its hydrocarbon successors.

The active ingredients of the present invention can also be applied with solid adjuvants or carriers such as talc, pyrophyllite, synthetic fine silica, attapulgus clay, kieselguhr, chalk, diatomaceous earth, lime, calcium carbonate, bentonite, Fuller's earth, cotton seed hulls, wheat flour, soybean flour, pumice, tripoli, wood flour, walnut shell flour, redwood flour and lignin.

As stated, it is frequently desirable to incorporate a surface-active agent in the compositions of the present invention. Such surface-active or wetting agents are advantageously employed in both the solid and liquid compositions. The surface-active agent can be anionic, cationic or nonionic in character.

Typical classes of surface-active agents include alkyl sulfonate salts, alkylaryl sulfonate salts, alkylaryl polyether alcohols, fatty acid esters of polyhydric alcohols and the alkylene oxide addition products of such esters, and addition products of long-chain mercaptans and alkylene oxides. Typical examples of such surface-active agents include the sodium alkylbenzene sulfonates having 10 to 18 carbon atoms in the alkyl group, alkyl phenol ethylene oxide condensation products, e.g., p-isooctylphenol condensed with 20 ethylene oxide units, soaps, e.g., sodium stearate and potassium oleate, sodium salt of propylnaphthalene sulfonic acid, di(2-ethylhexyl)ester of sodium sulfosuccinic acid, sodium lauryl sulfate, sodium decyl sulfonate, sodium salt of the sulfonated monoglyceride of coconut fatty acids, sorbitan sesquioleate, lauryl trimethyl ammonium chloride, octadecyl trimethyl ammonium chloride, polyethylene glycol lauryl ether, polyethylene glycol esters of fatty acids and rosin acids, e.g., Ethofat® 7 and 13, sodium N-methyl-N-oleyl taurate, sodium dibutylnaphthalene sulfonate, sodium lignin sulfonate, polyethylene glycol stearate, sodium dodecyl benzene sulfonate, tertiary dodecyl polyethylene glycol thioether (nonionic 218), long-chain ethylene oxide-propylene oxide condensation products e.g., Pluronic® 61 (molecular weight about 1000), polyethylene glycol ester of tall oil acids, sodium octophenoxyethoxyethyl sulfate, tris(polyoxyethylene)sorbitan monostearate (Tween® 60), and sodium dihexylsulfosuccinate.

The herbicidally effective concentration of the active ingredients in solid or liquid compositions generally is from about 0.00003 to about 95 percent by weight or more. Concentrations from about 0.05 to about 50 percent by weight are often employed. In compositions to be employed as concentrates, the active ingredient can be present in a concentration from about 5 to about 98 weight percent, preferably 15-50 weight percent. The active ingredient compositions can also contain other compatible additaments, for example, phytotoxicants, plant growth regulants, pesticides and the like and can be formulated with solid particulate fertilizer carriers such as ammonium nitrate, urea and the like.

In further embodiments, the compounds of the present invention or compositions containing the same, can be advantageously employed in combination with one or more additional pesticidal compounds. Such additional pesticidal compounds may be insecticides, nematocides, miticides, arthropodicides, herbicides, fungicides or bactericides that are compatible with the compounds of the present invention in the medium selected for application. In such embodiments, the pesticidal compound is employed as a supplemental toxicant for the same or for a different pesticidal use or as an additament.

The compounds of the present invention are particularly useful in combination with other herbicides including the substituted urea herbicides such as 3-(3,4-dichlorophenyl)-1,1-dimethylurea, 3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea (Lorox®) and 1,1-dimethyl-3-(α,α,α-trifluoro-m-tolyl)urea (Cotoran®); the triazines such as 2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine and 2-chloro-4-(1-cyano-1-methylethylamino)-6-ethylamino-s-triazine (Bladex®); the uracils such as 5-bromo-3-sec-butyl-6-methyluracil; N-(phosphonomethyl)glycine; the phenoxys such as 2,4-dichlorophenoxyacetic acid; picolinic acids such as 4-amino-3,5,6-trichloropicolinic acid (Tordon®) and 3,6-dichloropicolinic acid (Lontrel®); 4-chloro-2-butynyl-3-chlorophenyl carbamate (Carbyne®); diisopropylthiocarbamic acid, ester with 2,3-dichloroallyl alcohol (Avadex®); diisopropylthiocarbamic acid, ester with 2,3,3-trichloroallyl alcohol (Avadex® BVD); ethyl-N-benzoyl-N-(3,4-dichlorophenyl)-2-aminopropionate (Suffix®); 1,2-dimethyl-3,5-diphenylpyrazolium methylsulfate (Avenge®); methyl (2-[4-(2,4-dichlorophenoxy)phenoxy]propanoate) (Hoelon®); butyl 2-[4-[(5-(trifluoromethyl)-2-pyridinyl)oxy]phenoxy]propanoate (Fusilade®); esters of 2-[4-[(3 -chloro-5-trifluoromethyl)-2-pyridinyl)oxy]phenoxy]propionic acid; 4-amino-6-tert-butyl-3-(methylthio)-1,2,4-triazin-5-(4H)-one (Lexone®); 3-isopropyl-1H-2,1,3-benzothiadiazin-(4)-3H-one 2,2-dioxide; α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine; 1,1'-dimethyl-4,4'-bipyridinium ion; 2-chloro-2',6'-diethyl-(methoxymethyl)acetanilide; and 2-[1-(ethoxyimino)butyl]-5-[(2-ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one (Poast®).

The rates of application for compounds of the invention are determined by a number of factors including the active ingredient being applied, the particular action desired (e.g., general or selective control), the plant species to be modified and the stage of growth thereof, the part of the plant to be contacted with the toxic active ingredient, the formulation selected, weather and climate, etc. Thus, it is to be understood that all of the active ingredients of the present invention and compositions containing the same may not be equally effective at similar concentrations or against the same plant species. In non-selective preemergence and foliar treatments, the active ingredients of the invention are usually applied at an approximate rate of from about 0.01 to about 10 pounds/acre. In pre- and postemergence operations for selective uses, a dosage of about 0.01 to about 10 pounds/acre is generally applicable, a rate of 0.01 to 4 pounds/acre being preferred.

The following example illustrates the effect of the compounds of this invention applied postemergently.

The compositions, generally in the nature of an emulsion, were employed to spray separate respective plant species which had been grown to a 2-4 leaf stage in soil of good nutrient content in a greenhouse. Sufficient amounts were employed to provide various application rates as listed in the table. The various beds were positioned side by side and exposed to substantially identical conditions of temperature and light. Each bed was maintained so as to prevent any interaction with test compounds in different seed beds. Other plants were left untreated to serve as controls. After treatment, the plants were maintained for about two weeks under greenhouse conditions conducive for good plant growth and watered as necessary. The specific plant species, test compound and dosage and the percent postemergent control obtained are set forth in the table below. Control refers to the reduction in growth compared to the observed results of the same untreated species.

So as to clearly illustrate the phytotoxic properties of the various active ingredients of the present invention applied preemergently, a controlled greenhouse experiment is described below.

EXAMPLE 95

The seeds of various species of plants were planted in beds of good agricultural soil in a greenhouse. A number of compositions of the present invention, generally in the nature of an aqueous emulsion, were applied at rates listed in the table so as to deposit a predetermined amount of active ingredients uniformly throughout the surface of the bed. Another seed bed was treated only with water to serve as a control. After treatment the seed beds were maintained for two weeks under greenhouse conditions conducive for good plant growth and watered as necessary. The specific plant species, test compound, and dosage and the percent preemergent control are set forth in the table below. Control refers to the reduction in growth compared to the observed results of the same untreated species.

Certain of the compounds of this invention have been found to be useful for the control of aquatic weeds and some of these are useful for the selective control of, e.g., barnyardgrass and yellow nutsedge in paddy fields in the presence of rice. The following example illustrate the utility of the compounds of this invention in aquatic weed control.

EXAMPLE 96

In testing for such utility, the plant species to be tested were transplanted into 16 oz. containers into about 2 inches of soil when they were in the 1-2 inch stage and then flooded to a depth of about 1 inch. An acetone concentrate of the chemical to be tested was then injected into the paddy water, the volume injected being varied as desired to provide the desired concentration. Percent control was evaluated nine days after application. The results were as follows:

It has further been found that soil nitrogen may be conserved and plant nutrition improved by treating plant growth media with the novel compounds of this invention.

By the practice of the embodiment of the invention, the nitrification of ammonium nitrogen in the soil to nitrate nitrogen is suppressed, thereby preventing the rapid loss of ammonium nitrogen from the soil. Furthermore, by proper distribution of the novel compounds, this action of inhibiting the transformation of ammonium nitrogen to nitrate nitrogen is effective over a prolonged period of time including those situations where treated fertilizer is stored for some time before use. The ammonium nitrogen may arise from added ammonium nitrogen fertilizers or be formed in the soil by conversion of the organic nitrogen constituents found in soil or added thereto as components or organic fertilizers.

The provision of an effective but sublethal dosage of the active ingredient in the soil or growth medium is essential for the practice of the present invention. In general, good results are obtained when the growth medium is impregnated with the active ingredient in the amount of from 0.01 part to 100 parts or more by weight per million parts by weight of growth medium. (Hereinafter, the abbreviation ppm when employed is meant to designate parts by weight of active ingredient per million parts by weight of soil or growth medium.) The preferred amounts to be employed are dependent upon the particular situation. Thus, in determining the amount to be employed, consideration is made not only of the treatment need, i.e., soil pH, temperature, soil type, etc., but also of the mode of application to the soil. When the active ingredient is to be applied in a broadcast application, the concentration may frequently be less than in row or band application where for a substantial depth and width within the vicinity of application there may be a very high concentration of the active ingredient. When application is made near the root zone of growing plants or when application is made immediately prior to seeding or transplanting, the amounts supplied are frequently at a lower rate than when application is made at the end of the growing season to prepare the soil for the following season. By dispersing very large dosages in growth media, a prolonged inhibition of nitrification may be obtained over a period of many months. The concentration of the active ingredient is eventually reduced to a minimum by decomposition in the soil.

In one method for carrying out this embodiment of the invention, the active ingredient is distributed throughout the growth media in a broadcast application such as by spraying, dusting, distributing in irrigation water, etc. In such application, the active ingredient is supplied in amounts sufficient to permeate the growing area of soil with an amount of from 0.05 to 1000 ppm. In field administration, the active ingredient may be distributed in the soil in the amount of at least 0.05 pound per acre (0.056 kg/hectare) and through such cross-section of the soil as to provide for the presence therein of an effective concentration of the agent. It is usually preferred that the active ingredient be distributed to a depth of at least two inches (5.08 cm) below the soil surface and at a dosage of at least 0.1 pound per acre (0.112 kg/hectare).

In another method for carrying out the present invention, the active ingredient is administered to the growth medium in a band or row application. In such application, administration is made with or without carrier in an amount sufficient to supply to soil or growth medium a concentration of the active ingredient which may be as high as 4000 ppm or more. After administration with or without discing or dragging, subsequent irrigation or rainfall distributes the active ingredient throughout the growth medium.

In one embodiment of the present invention, the active ingredient is distributed throughout the growth media prior to seeding or transplanting the desired crop plant.

In another embodiment, the soil in the root zone of growing plants is treated with the active ingredient in an amount effective to inhibit nitrification. Oftentimes, it is desirable to treat the soil adjacent to plants, and this procedure may be carried out conveniently in side-dressing operations.

In a further embodiment, soil may be treated with the compounds following harvest or after fallowing to prevent rapid loss of ammonium nitrogen and to build up the ammonium nitrogenformed by conversion of organic nitrogen compounds. Such practice conserves the soil nitrogen for the following growing season. In such application, the upper limit is primarily an economic consideration.

In an additional embodiment, the soil is treated with the active ingredient in conjunction with the application of reduced nitrogen fertilizers. The treatment with the active ingredient may be carried out prior to, subsequent to or simultaneously with the application of fertilizers. Such practice prevents the rapid loss of the ammonium nitrogen added as fertilizer and of the ammonium nitrogen formed from organic nitrogen in fertilizers by the action of soil microorganisms. The administration to the soil of the active ingredient in an ammonium nitrogen or ammonium nitrogen forming fertilizer composition constitutes a preferred embodiment of the present invention.

The present invention may be carried out by distributing the active ingredient in an unmodified form through growth medium. The present method also embraces distributing the active ingredient as a constituent in liquid or finely divided solid compositions. In such practice, the active ingredient may be modified with one or more additaments or soil treating adjuvants including water, petroleum distillates or other liquid carriers, surface-active dispersing agents, finely divided inert solids and nitrogen fertilizers. Depending upon the concentration of the active ingredient, such augmented composition may be distributed in the soil without further modification or be considered a concentrate and subsequently diluted with additional inert carrier to produce the ultimate treating composition. The required amount of the active ingredient may be supplied to growth media in an organic solvent carrier, in an aqueous carrier or in a solid carrier. When an organic solvent carrier is employed, it may be further dispersed in an aqueous liquid carrier.

The concentration of the active ingredient in compositions to be employed for the treatment of growth media is not critical and may vary considerably provided the required dosage of effective agent is supplied to the growth media. The concentration of the active ingredient may vary from 0.00001 percent by weight to 95 percent by weight of the composition, depending on whether the composition is a treating composition or a concentrate composition and whether it is in the form of a solid or a liquid. In aqueous liquid treating compositions, concentrations of from 0.00001 percent to 0.25 percent by weight of the active ingredient is considered the preferred composition. The concentration of the active ingredient in organic solvents may be from 2 to 95 percent by weight. Concentrate liquid compositions generally contain from 2.5 to 95 percent by weight of the active ingredient. Treating compositions generally contain from 0.0001 percent to 10 percent by weight of the active ingredient while concentrate compositions contain from 2.5 to 95 percent.

Liquid compositions containing the desired amount of the active ingredient may be prepared by dispersing the latter in one or more liquid carriers such as water or an organic solvent, with or without the aid of a suitable surface-active dispersing agent or emulsifying agent. Suitable organic solvents include acetone, diisobutylketone, methanol, ethanol, isopropyl alcohol, toluene, methylene chloride, chlorobenzene and the petroleum distillates. The preferred organic solvents are those which are of such volatility that they leave little permanent residue in the soil. When the solutions of the active ingredient in organic solvents are to be further diluted to produce aqueous dispersions, the preferred solvents include acetone and the alcohols. When the liquid carrier is entirely organic in nature, particularly desirable carriers are the petroleum distillates boiling almost entirely under 400° F. (204° C.) at atmospheric pressure and having a flash point above 100° F. (38° C.). Dispersing and emulsifying agents which may be employed in liquid compositions include condensation products of alkylene oxides with phenols and organic acids, alkyl aryl sulfonates, polyoxyalkylene derivatives of sorbitan esters, complex ether alcohols, mahogany soaps and the like. The surface-active agents are generally employed in the amount of from 1 to 20 percent by weight of the active ingredient.

Solid compositions containing the active ingredient may be prepared by dispersing the latter in finely divided inert solid carriers such as talc, chalk, gypsum, vermiculite, bentonite and the like, fuller's earth, attapulgite and other clays, various solid detergent dispersing agents and solid fertilizer compositions. In preparing such compositions, the carrier is mechanically ground with the active ingredient or wet with a solution or dispersion thereof in a volatile organic solvent. Depending upon the proportions of ingredients, these compositions may be employed without further modification or be considered concentrates and subsequently further diluted with solid surface-active dispersing agent, talc, chalk, gypsum or the like to obtain the desired treating composition. Furthermore, such concentrate compositions have the properties of wettable powders and may be dispersed in water with or without added dispersing agent or agents to prepare aqueous soil treating compositions.

Soil treatment compositions may be prepared by dispersing the active ingredient in fertilizers such as ammonium fertilizer or organic nitrogen fertilizer. The resulting fertilizer composition may be employed as such or may be modified as by dilution with additional nitrogen fertilizer or with inert solid carrier to obtain a composition containing the desired amount of active agent for the treatment of soil. Further, an aqueous dispersion of the active ingredient-fertilizer composition may be prepared and administered to the growth medium. Fertilizer compositions comprising the active ingredient in intimate admixture with ammonium fertilizers constitute preferred embodiments of the present invention.

In fertilizer compositions comprising a reduced nitrogen fertilizer, it is desirable that the active ingredient be present in an amount of at least 0.05 percent by weight based on the weight of the nitrogen present in the fertilizer as reduced nitrogen and may be present in amounts as high as 95 percent by weight of the reduced nitrogen in the fertilizer. Thus, when a fertilizer composition contains both reduced nitrogen and other forms of nitrogen such as in the case of ammonium nitrate fertilizer compositions, the amount of the active ingredient is based on the weight of nitrogen present in the ammonium component.

In operations carried out in accordance with the present invention, the soil may be treated in any convenient fashion with the active compound or a composition containing the latter. For example, these modified or unmodified compositions may be mechanically mixed with soil; applied to the surface of soil and thereafter dragged or disced into the soil to a desired depth; or transported into the soil with a liquid carrier wuch as by injection, spraying or irrigation. When the distribution is carried out by introducing the compound in the water employed to irrigate the soil, the amount of water is varied in accordance with the moisture content of the soil in order to obtain a distribution of the compound to the desired depth. The compound may be readily and conveniently distributed to a depth of a few inches to four feet by irrigation methods. The preferred methods embrace procedures using any of these steps or combination of steps wherein the compound is distributed in the soil substantially simultaneously with a reduced nitrogen fertilizer.

A number of the compounds of this invention were tested for their ability to reduce the rate of nitrification of ammonium nitrogen, applied as ammonium phosphate to the soil. The activity is reported in the following table.

EXAMPLE 97

The test method comprised selecting a soil which had a low nitrate concentration and good nitrification activity. A sufficient volume of water was added to 20 g of the soil in a wide-mouth, screw-cap, 4-ounce, glass bottle, such that the moisture content of the mixture was made equal to the 1/3 bar tension value for that soil. The mixture was thoroughly mixed before sealing. The added water contained 5 mg (250 ppm) of nitrogen in the form of (NH₄)₂ HPO₄ (23.6 mg of ammonium phosphate) and the desired quantity of test chemical (i.e., 20 mg for a 1 ppm concentration based on dry weight of soil). When the test chemical had a low water solubility, it was compounded in acetone (or other suitable solvent) in such a way that the final mixture in the soil contained to more than 10 μl of acetone. Acetone slows the rate of soil nitrification and its concentration must be carefully controlled. Single samples of each test chemical were incubated for two weeks at 27° C.

The experiment comprised the following types of samples:

1. Nitrate blank containing soil, water and solvent only. (BLANK)

2. Test chemicals containing soil, water, ammonium phosphate, solvent, and test chemical. Single samples. (SAMPLE)

3. Nitrate control containing soil, water and ammonium phosphate only. (CONTROL)

The soil samples were analyzed as follows: Sufficient ammonium sulfate extracting solution was added to the sample, such that the total volume of added water was 50 ml (included water added during sample preparation). The capped mixture was shaken 10 minutes to solubilize nitrate and the soil particulates were allowed to settle. The nitrate concentration in the water phase was determined with a nitrate-specific ion electrode such as Orion Model 93-07.

The non-nitrate nitrogen remaining (% NH₄ -N remaining) in the soil after two weeks (performance value) was calculated as follows: ##EQU1##

Additionally, certain compounds of the present invention may be used to modify plant growth benefically such as the inhibition of bolting in sugarbeets. Other compounds of the present invention alter the normal growth of sugarbeets by stunting the plant. Both of the effects described above are not accompanied by any phytotoxic symptoms.

Sugar beet flowering is controlled by a cold weather treatment of the plants (vernalization) followed by long days. As the days lengthen, the beets produce bolters--elongated stems bearing flowers--and ultimately seeds on indeterminate, multibranced racemes. In Europe where a large acreage of sugar beet is grown, cold spring weather following sowing is often enough to induce bolting of the beets. This bolting causes various problems to the farmer who grows the beet for the sugar content of the beet root. The problems are numerous:

1. Bolting reduces both the size and the sugar content of the beet root since the products of photosynthesis are diverted to flower production.

2. Bolting causes processing difficulties due to lignification of the root. Lignification uses up stored sugars as well, thus reducing the efficiency of the extraction process.

3. Bolters physically interfere with mechanical harvesting by becoming entangled in harvesting machinery.

4. Bolted plants cause a large amount of competition by shading of adjacent plants, thereby reducing their root size.

5. With time, the seed from early bolters have produced a weed beet with an annual habit requiring little or no vernalization. This weed beet, besides causing severe competition, prevents "beet-free periods" which are necessary for the control of beet yellowing virus.

If bolting could be completely prevented, this would be a possible means of realizing the potential physiological advantages of autumn sowing. Greater utilization of the season would be achieved by the capturing or radiation which normally falls on bare ground. Yield increases of up to 25% have been predicted from autumn as opposed to spring sowing. Even an earlier spring sowing promises an increase in yield. The following example illustrates the plant growth regulator effects of the compounds of this invention.

EXAMPLE 98

Using a regular biennial variety, even a bolting-susceptible variety would require a cold treatment of around 10-16 weeks plus a hormone treatement in conjunction with specific light intensities. Thus, for a screening organism, we selected one which would consistently produce bolting on a regular schedule. The screen is run with an annual sugar beet variety (SLC03) provided by Dr. Richard J. Hecker, Fort Collins, Colo. This variety is an inbred which bolts in the 6- to 8-leaf stage without any need for vernalization. This allows the screen to be run entirely in the greenhouse with all 110 chemical compounds tested on one tray. The sugarbeets are grown in 3×3 inch square pots in a greenhouse sandy loam potting mix. The sugarbeets are sprayed with test compounds when they are 2 to 3 weeks old (2 true leaves). The compounds are dissolved in acetone and diluted with water containing Tween 20 as a wetting agent. The concentration of acetone in the final spray is 20% and the concentration of Tween 20 is 0.05 percent. The plants are examined for the appearance of a bolt 4 weeks after spraying.

Preemergence tests are conducted by spraying formulated chemical on seeds placed on potting soil. The sprayed seeds are then covered with 1/4 inch of potting soil and the pots are watered. Bolting is evaluated 6-7 weeks after the initiation of the test. At this time untreated plants have a vigorous bolting stem with visible flowers.

EXAMPLE 99

The compounds of this invention are also plant gametocides depending on the dosage and timing of application and the species of plant to which the compounds are applied. For example, certain of the compounds were sprayed on corn seedlings at the three leaf stage of growth, and the seedlings were returned to the greenhouse for subsequent growth and observation. The corn variety was "First In". The chemicals were dissolved in acetone, and the acetone solution was diluted with water containing Tween 20 wetting agent such that the final spray solution contained 50% acetone and 0.1% Tween 20 in water. At the time of tassel formation the anthers appeared normal, but they did not contain pollen. Tabulated below are data which illustrate the use of the compounds of this invention as plant gametocides in corn.
